hi,it seems that we need to rewrite the howto.You have to unpack the tar file first. It contains a loader for Cl4 and SLC class devices. You unfortunate flashed the tarball directly. With jtag you should be able to flash the right loader to the pad.

The cable looks ok, but I don't know how it is wired. So I cannot guarantee that it will fit. You also need to solder the connector to the pad.
